Dr Julian W Tang, Clinical Virologist, University of Leicester explains the importance of wearing masks in public and how it can help fight COVID-19 and its variants like Omicron. He says, "Masking is very effective. If we have even one person wearing a mask properly, it will reduce the chances of getting infected with COVID-19 by 25 per cent and if both people are masking then it reduces the chances of getting infected with COVID-19 by 60 per cent."
